HORN FOR PEGGlNG-MACHINES.

SPIEl-GIFIOATIUN forming part of Letters Patent N 0. 667,928, datedFebruary 12, 1901.

Application filed October 23, 1900. Serial No. 34.065. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN E. BICKFORD, of Whitman, in the county ofPlymouth and State of Massachusetts, have invented a new and usefulImprovement in Horns for Pegging-Machines, of which the following, takenin connection with the accompanying drawings, is a specification.

My invention relates to that class of horns that rot-ate and areprovided with means for cutting off the projecting ends of the pegs; andit consists in the peculiar mechanism used for producing the resultdesired, the object being to make a simple and effective mechanism forsupporting the boot or shoe and for cutting the pegs. This object Iattain by the means illustrated in the accompanying drawings, in which-Figure 1 is a view partly in vertical section and partly in elevation.Fig. 2 is a crosssection taken on line 2 .2 of Fig. 1. Fig. 3 is a planview of the knife. Fig. at is a side view of the knife, a part beingshown in section.

In the drawings a part of the frame of the machine is indicated by A A,and the post, which supports the horn, is designated by P. This postdoes not turn, but may be raised and lowered. The horn B B B is mountedupon the post P and is free to rotate upon it. The upper end of the hornhas a stationary knife B which fits onto the end of the horn, as shown,and is secured by the screw B. A peg-hole b is made in the knife B Thishole is beveled, so as to present a knife-edge to the peg. The lowerknife is indicated by K, Figs. 1, 8, and 4-. This knife is adapted tofit closely to the under side of the stationary knife B and has a holeIt, also beveled, as shown, so that as it slides it, together with thestationary knife B will cut the peg with a shearing cut. Thisarrangement of the stationary knife B and the moving knife K insures anexact easy action of the k nives,which results in cutting out the pegsin a thorough manner. The moving knife K is operated by thefollowing-described mechanism: A bent rod D D has a pin .D at its upperend, With which the knife if by its hole K engages, so that any movementof the bent rod D D will be transmitted to the said knife. The bent rodD D slides up and down in a groove made in the horn (see Fig. 2) and isheld in place by the plates E E.

The lower end D of the rod D D is connected to a rod R by means of a nutR and check-nut B A spring S serves to press the bent rod D D upward.The lower end of the rod R has rigidly attached to it a forked arm R Rupon which a friction-roller R is mounted. The roller R rests upon thecamsurface of the fixed cam C, so that byswinging the arm R a verticalmovement will be imparted to the rod R and through it to the bent rod DD and thence to the knife K. The cam O is rigidly attached to the post Pby means of the set-screw O and moves with the said post and also withthe horn in vertical motion; but the horn is free to rotateindependently of the post and the cam C.

To give the forked arm R a swinging motion, I have a lever L L, whichhas an adjustable fulcrum-pin L which is held to it by the nut andcheck-nut L The fulcrumpin L is attached to an adjustable slide L whichis adjustably attached to the fixed arm A of the frame A of the machineby a bolt L which passes through a slot made in the slide L Motion isimparted to the lever L L by a lever N, which is operated by a cam onthe pegging mechanism of the machine. The lever L is made adjustable inorder to allow for the wear of the parts as the machine is used.

The vertical part L of the lever L L is made long so that the downwardmovement of the post and horn, necessary for putting on and taking off ashoe, will not disengage it from the fork R of the forked arm R R Thesliding knife K may have a straight cutting edge and the hole It beomitted, if desired.

I claim-- 1. A born for pegging-machines comprising a knife for cuttingoff the pegs: mechanism for connecting said knife with a swinging arm:and said swinging arm: a cam fixed upon the horn-supporting post of themachine and having an inclined surface which will cause the saidswinging arm to be vertically operated thereby giving motion to theknifeoperating mechanism substantially as and for the purpose set forth.

swinging arm: and mechanism for operating said adjustable leversubstantially as and for the purpose set forth.

In testimony whereof I have signed my 15 name to this specification, inthe presence of two subscribing Witnesses on this 13th day of October,A. D. 1900.
